When Sir George Caley fastened two kites together with a stick he invented the __________. glider The person often called the "father f modern aviation" is ____________. Otto Lilienthal Early experimenters though that mysterious gases from open fires made balloons rise into the air. what really made it rise was the _______ _______. Hot air When an object travels through the air using wings to give lift flying An object that will rise until they displace their own weight of air balloons The difference between a dirigible and a zeppelin is that the zeppelin has(1) ________ gas bags and a(2) _____ frame. (1) several (2) rigid The angle at which a kite flies causes a ______ to form on top, providing lift. vacuum Wings that have a curve to them cambered In modern planes a curved wing is called an _____. Airfoil (IMPORTANT) the faster the speed of air, the LOWER its pressure becomes. This relationship is called ________ _________. Bernoulli's Principle When air passes over an airfoil, the air that passes over the top travels farther. Therefore, the air pressure on the top of the wing is ____ than the pressure on the bottom of the wing. lower When an airfoil doesn't have enough lift it will ______ and fall to the ground. stall The forward motion of an airplane provided by the engine is called __________. thrust On reciprocating engines, fuel is exploded in the __________by spark plugs. cylinder jet engines are called _____ engines. reaction in ALL jet engines the ultimate reason a plane moves forward is a result of ________ gases. expanding The main difference between a turbojet and a turboprop engine is that in a turboprop, a _______ gives additional thrust to the engine. propellor Airplanes can turn on ______ axes of rotation. three The up and down movement of the nose is called _______. Pitch Side to side motion is called _____. yaw ________ tries to pull the plane down. gravity _____ causes friction as the plane moves through the air. drag _______ is the action you get when you pull or push the wings through the air. lift All controlled surfaces are ____________________. moving parts _______ is a control surface found in the vertical stabilizer. rudder _______ is the control surface found in the horizontal stabilizer. elevator the wing of a helicopter has several blades and is called ________. rotors Planes that can take of vertically (straight up) are called________. VTOL Vertical take off landing The traffic around an airport is controlled for a radius of _____ miles. 5
